Heavy Metals Monitoring Applications

  • Detection of specific heavy metal content in water

    Detection of heavy metal concentration in water, sea water, environmental waters and pre-treated waste water to low PPB levels using a hand held fluorimeter. Test results acquired within one minute. Technology uses DNAzyme based fluorimetric detection.

  • Wastewater treatment for the metallurgic industry

    Waste water in this sector has a high concentration of heavy metals, oils and products in decomposition. The oils and emulgents lead to foam production at the water treatment plants. The treatment of these oils is very important.

  • K&S performs Solarpark supervision in Japan to secure high quality standards

    The team of K&S technical experts perform independent technical inspections of the photovoltaic system and clarifies technical issues. The advisory service begins even before the actual construction of the photovoltaic power plant - in the design and contract review. It is ensured that all the requirements of the building permit of the relevant Japanese authorities are fulfilled and the contract is aligned with the system. Based on the continuous construction and factory acceptance tests of components, possible quality defects from the start can be reduced to an absolute minimum. With the local networks of the Japanese technology institutions such as New Energy and Industrial Technology Development Organization (NEDO), Japan Electrical Safety & Environment Technology Laboratories (JET), Japan Photovoltaic Energy Association (JPEA) and other leading technology institutions, K&S combines a comprehensive local technical advisory service in Japan.

    Process water

    Process water is one of the most challenging for analysis instrumentation. Mostly this water is characterized by a certain purity, fluctuating loads, as well as very high salt concentrations. Since any disturbance in water-circuits can lead to an entire plant shutdown, resulting in huge costs, reliable and fast online water analyzers are an essential. Due to the diverse demands of various measurement challenges, application-specific analyzers provide huge advantages against standard analyzers that are used for every application.

    Metal Precipitation

    When used as part of a wastewater treatment program, Remotox (calcium polysulfide) can effectively reduce and precipitate a wide range of heavy metals. This product has proven effective even when treating chelated and/or complexed metals. Its unique formulation also removes chromates and dichromates without preliminary reduction of the chromium to the trivalent state.

  • Quantitative Analysis of Steel Using Laser Induced Breakdown Spectroscopy (LIBS)

    For steel analysis, LIBS is ideal for rapid QC (quantitative analysis and detection of contaminants) for raw materials in production, and to check the elemental composition of finished products. LIBS also offers the ability to analyze slag samples that can lead to the recovery of precious metals lost in the steel production process.

    Recycling and processing of shredder heavy fraction

    Since 1991, the bi-directional dense medium separation technology for the recycling of automobile and industrial wastes is being used. For many years a principle client in this regard has been the Group Galloo.  Group Galloo owns currently 50% of the AD REM shares. At first the Galloo staff was not convinced that a carrot separator could compete with the classical dense medium separators on the market at that time. So they set up a trial on +12 mm automobile shredder residue, running half of the test material through a conventional drum and the other half through this modified bi-directional carrot separator.

    Gas monitoring instruments and systems for nickel refining

    The mining industry uses chemicals as ‘flotation’ agents in the recovery of sulphide minerals containing metallic elements (e.g., copper, nickel, silver, gold) from ore slurries. Sodium ethyl xanthate (SEX) is one of most common flotation agents, and it decomposes to form ethanol, carbon disulfide CS2, and Carbonyl Sulfide COS. These harmful gaseous compounds must be monitored from the indoor air at the enriching plant.

  • Coal Combustion Residuals Disposal for Power Plants

    Coal combustion residuals (CCR) are generated during the power generation process and can include fly ash, bottom ash, boilerslag, and flue gas desulfurization (FGD) residuals. CCRs contain trace concentrations of heavy metals and therefore cannot be dumped or stored where rainwater can leach the metals. Liner systems can be used to contain the coal combustion by-products and protect them from leaching into the environment.

    Water Treatment Solutions for Turbidity Removal

    Turbidity is a measure of the loss of light transmittance through a liquid due to suspended particles. The more particles in the water, the murkier it looks or the higher the turbidity. This is a measure of the quality of the water. It is measured in units called Nephelometric Turbidity Units (NTU). Turbidity can be caused by run off after a heavy rain as erosion washes soil into a river or lake. It is often increased in the spring and fall when the water temperature at different levels in a lake change causing a turnover of those levels, bringing sediment, plants, and algae to the top.
